510 rather unsightly appearance and, as the -avor is lost as quickly inthe large amount of gum as in the smaller amount, many persons prefer tochew only part of a. stick at a time. Consequently, as a matter ofconvenience, only half 15 of a stick is used;. this is usually obtainedby tearing in two pieces one of the ordinary, wrapped sticks. Theremaining half stick, if it is to be preserved,must be placed in thepocket,

or hand bag, until it is to -be put to use. This is,v

objectionable, rst, the open stick of gum may soil the pocket, or itemsin handbags, and secondly, it quite often picks u p materials whichadhere to' the vexposed gum.

In considering a diierent packaging for gum, however, it becomes evidentthat a change in the general type of. package will bring about a greatinconvenience and loss, particularly in the vending machine business,and, secondly, in the better types of stores where display anddispensing cabinets are already provided for the.

commonlyaccepted types of gum packages.

As a solution for this problem I have provided a new package for gumconsisting of a plurality of half sticks, individually wrapped, and soarranged under a single wrapper that the general proportions and size ofthe ordinary gum package is retained, yet is so arranged that theenclosing wrappers ofthe package can easily be removed.

This, in turn calls for a special packaging, or arrangement, of theenclosing wrapper which 1 produces my duplex package.A In this I providemeans for opening the outer covering of my package with aconvenient'tearing strip in which the tape providing the tearing mediumserves to hold the outside wrappers of the individual sticks definitelyin place until the outside wrapper is removed.

The principal object cf my present invention, therefore, is to provide aduplex package in which with the maximum convenience and with'theminimum opportunity for contamination of the gum, I provide a 'servingof a size most readily acceptable tothe average user.

A further object of my present invention is\to ggprovide meansi'orinitially, hermeticallysealjig (ci. ser-iso) a gum package, whichmay be easily divided into two separate packages, in which all thereduced size sticks'are still provided with a completely enclosing coverand outer wrapper for holding the cover in place. l

A Iurtherobject is to use a tearing strip sufliciently wide to tear thewrapper away on both units oi the duplex package to make it possible toeasily separate a stick ,otgum from a unit.

Other and more specic objectsl will be apparl0 .ent from the followingdescription taken in con- \nection -with the accompanying drawings,-

Figure 13 illustrates the package of Figure 11 with the'c'overing ofFigure 12 in place thereon.

lFigure 14 is 4a perspective view showing the outer covering or envelopewhich with certain ,of packages, is desirable and which is Il placedover the entire package I 3 to produce the nal result shown in Figure 1.

Referring to the drawings, throughout which like reference charactersindicate like parts, I6

5 designates my gum stick. 'This I form of suhstantially the same crosssection as the conventional gum stick, but instead of being the lengthnormally sold, I prefer that it shall be approximately one-half of thatlength. This. size, it l has been proved, is most acceptable to theaverage user, not causing breaking, folding or biting off, since it is aconvenientsize to putin the mouth. Each stick I6 is individually wrappedin an, inner cover as I8; this wrapper should be l made of materialnormally employed for this purpose. In Figure 8 I have shown, in dashedline, the lines upon which the folds are made. When the inner wrapper I8is in place the appearance of the stick is shown in Figure 9 which willillustrate clearly,` it is believed, the method of folding wrapper I8thereon.

The next operation is to place on the wrapped' stick, the outer wrapper,or binder, 20. This binder, when. in place after the showing of FigureI0, completes the individual sticks wrapping and follows more or lessconventional lines in that the width of wrapper 20 is appreciably lessthan the over all length of stick I6 so that when it is desired to openone such stick, the

wrapper 20 may be grasped and the stick, with its inner wrapper, shovedendwise` within the outer wrapper after the normal practice so as tomost easily unwrap the stick.

In producing a retail `package I abut a plurality of sticks I6 after theshowing of Figure 11.

This provides a considerable gap in the wrappers 20 at the center of thepackage owing to .the fact that we now have double the end space v ofone stick.

Around the package shown in Figure 11 I next provide the inner packagewrapper shownin Figure 12. This may consist of two half-wrappers as 22and 24 which are joined together as by tape 26. For this purpose anysuitable tape l may be used; however, that made after the' order of the'so-called Scotch to be highly satisfactory. serves a dual purpose inmember for portions 22 and 24 and also to reinforce the package at itscenter where it is normally weakeneddue to the fact that covers 20of theindividual sticks, stop somewhat bcfore reaching the center lineof the`package. When the Wrapper shown in Figure 12 is in place 55 the packagewill then appear as shownin Figure 13. This wrapper is normally oftreated paper and will usually carry the trade name and detape has beenfound This tape, therefore,

scriptive matter ordinarily appearing on a package. v 00 The nextoperation is .the placing of the outer or enclosing wrapper or envelope28. I'his is shown in Figure 14 and the folding lines are also indicatedin dashed lines. When this wrapper is in place the final appearanceofthe @t package is as illustrated in Figure 1. 'Ihe exact position of thevarious wrappers will probably be best understood froml a study of'Figures 2 and 5. Cover- 28' shown in Figure 14 is normally made oitransparent, cellulose material typical of which is "Cellophane and inorder to start a tearing of the cover it has been found desirable toscore or, preferably, slit the material slightly as at 30, after whichit has been found that the material will tear very 1| readily. I

providing a joining With certain types of covering and for a certainmarket it may be desirable to provide the inner covering shown in Figure12 as a single sheet having very short slits similar to those of sheet28; when this is done vthe tape 26 should i rest on the individual stickcovering using a non-adhesive tape, or using an adhesive tape, such asthe so-called Scotc tape, the tape is applied to the inside surface ofthe single sheet as is illustrated in Figures 6 and 7, so that 10 whenit is desired to openrthe package, tape 26 will provide the parting ortearing medium for both the inner wrapper of the main package and theouter wrapper or envelope. In either form of wrapping, however, theoutward appearl5 ance of the package will be as illustrated in Figure 1,in which an end of tape 26 will extend out of the package from under thewrapping so that it may be conveniently grasped; or if found moreconvenient for machine adaptation, with m the use of a single innersheet a hole may be punched in the outer wrapper through which the tapewill extend.

Method of operation u In opening a package of gum, wrapped after the`teachings of my present invention, I find a very convenient position tobe that illustrated in Figure 3 wherein the packageitself is grasped asillustrated so that it can revolve in the hand. 30 The end of tape 26 isthen grasped by the free hand, and, as itis pulled and the packageitself permitted to revolve, the outer wrapper, or envelope, and theinner main package wrapper will be parted at the center of the packageso 35 as to provide the two half packages as illustrated inFigure 4.Each of these packages will contain. a plurality of sticks each with itsown completely enclosing wrapper. Each of the two half packages'will be-a compact, stable unit either 40 of winch may be carried in the pocketwith reasonable assurance that the sticks will not become dislodged evenafter one of the same has been removed from the half package. In soforming a package, aside from the convenience 45 of giving the consumera stick of suitable size,

it provides an easy means of dividing a package of gum. This is ofconsiderable advantage when a couple may wish to divide a package orwhere it is desirable to divide gum for children 50 or the like.

It will be apparent it is believed that once the duplex` package hasbeen parted so as to produce the two half packages the individual sticksmay then be removed in the normal man 55 ner.

While I have confined my description and illustration throughout thisspecification to packaging of gum, it is believed it will be apparentthat this form of packaging might be applied 30 to many other productseven aside from confections and gum. Y

The foregoing description and the accompanying drawings are believed toclearly disclose a preferred embodiment of my invention but it'cs willbe understood that this disclosure is merely illustrative and that suchchanges in the invention may be made as are fairly within the scope -andspirit of the following claims.

Having thus fully described my invention. what 70 I claim as new anddesire to secure by Letters Patent is: 1 1.
